Improving VO2max through blood protein analysis

My wife and I have recently bought new smartwatches (me: Garmin Venu 2, her: Fitbit Versa 3) and the things they tell us really makes a difference to how we exercise. What’s reported here looks like next level even to the detailed stats we’ve got already.

The team identified a set of 147 proteins that could indicate a person’s VO2max, a marker of cardiorespiratory fitness, before the exercise program, and then a set of 102 proteins that could indicate the change in VO2max after it had been completed. Some of these proteins were also found to be linked to a higher risk of early death, highlighting a connection between cardiorespiratory fitness and long-term health.

“We identified proteins that emanate from bone, muscle, and blood vessels that are strongly related to cardiorespiratory fitness and had never been previously associated with exercise training responses,” says Gerszten.

Based in these revelations, the scientists developed what they call a protein score, which could be used to predict how much a person’s VO2max would change as a result of the exercise. Baseline levels of certain proteins were able to predict who would respond to the exercise with more reliability than established patient factors, according to the scientists, and also predicted which subjects would be unable to significantly improve their VO2max even after a sharp uptake in physical activity.

The World’s Oldest Story? Astronomers Say Global Myths About ‘Seven Sisters’ Stars May Reach Back 100,000 Years — “Why are the Australian Aboriginal stories so similar to the Greek ones? Anthropologists used to think Europeans might have brought the Greek story to Australia, where it was adapted by Aboriginal people for their own purposes. But the Aboriginal stories seem to be much, much older than European contact. And there was little contact between most Australian Aboriginal cultures and the rest of the world for at least 50,000 years. So why do they share the same stories?”

(Yes, even when the sky is resolutely leaden, it is still technically daylight.) Walking warms you up, too; when you get back indoors, it will feel positively tropical.”

🔐 How Law Enforcement Gets Around Your Smartphone’s Encryption — “Cryptographers at Johns Hopkins University used publicly available documentation from Apple and Google as well as their own analysis to assess the robustness of Android and iOS encryption. They also studied more than a decade’s worth of reports about which of these mobile security features law enforcement and criminals have previously bypassed, or can currently, using special hacking tools.”

😲 The Ethics of Emotion in AI Systems (Research Summary) — “There will always be a gap between the emotions modelled and the experience of EAI systems. Addressing this gap also implies recognizing the implicit norms and values integrated into these systems in ways that cannot always be foreseen by the original designers. With EAI, it is not just a matter of deciding between the right emotional models and proxy variables, but what the responses collected signify in terms of human beings’ inner feelings, judgments, and future actions.”

Friday fashionings

When sitting down to put together this week’s round-up, which is coming to you slightly later than usual because of <gestures indeterminately> all this, I decided that I’d only focus on things that are positive; things that might either raise a smile or make you think “oh, interesting!”

Let me know if I’ve succeeded in the comments below, via Twitter, Mastodon, or via email!


Digital Efficiency: the appeal of the minimalist home screen

The real advantage of going with a launcher like this instead of a more traditional one is simple: distraction reduction and productivity increases. Everything done while using this kind of setup is deliberate. There is no scrolling through pages upon pages of apps. There is no scrolling through Google Discover with story after story that you will probably never read. Instead between 3–7 app shortcuts are present, quick links to clock and calendar, and not much else. This setup requires you as the user to do an inventory of what apps you use the most. It really requires the user to rethink how they use their phone and what apps are the priority.

A year ago, I wrote a post entitled Change your launcher, change your life about minimalist Android launchers. I’m now using the Before Launcher, because of the way you can easily and without any fuss customise notifications. Thanks to Ian O’Byrne for the heads-up in the We Are Open Slack channel.


It’s Time for Shoulder Stretches

Cow face pose is the yoga name for that stretch where one hand reaches down your back, and the other hand reaches up. (There’s a corresponding thing you do with your legs, but forget it for now—we’re focusing on shoulders today.) If you can’t reach your hands together, it feels like a challenging or maybe impossible pose.

I was pretty shocked that I couldn’t barely do this with my right hand at the top and my left at the bottom. I was very shocked that I got nowhere near the other way around. It just goes to show that those people who work at home really need to work on back muscles and flexibility.


Dr. Seuss’s Fox in Socks Rapped Over Dr. Dre’s Beats

As someone who a) thinks Dr. Dre was an amazing producer, and b) read Dr. Seuss’s Fox in Socks to his children roughly 1 million times (enough to be able to, eventually, get through the entire book at a comically high rate of speed w/o any tongue twisting slip-ups), I thought Wes Tank’s video of himself rapping Fox in Socks over Dre’s beats was really fun and surprisingly well done.

One of the highlights of my kids being a bit younger than they are now was to read Dr. Suess to them. Fox in Socks was my absolute tongue-twisting favourite! So this blew me away, and then when I went through to YouTube, the algorithm recommended Daniel Radcliffe (the Harry Potter star) rapping Blackalicious’ Alphabet Aerobics. Whoah.

Google launches free version of Stadia with a two-month Pro trial

Google is launching the free version of its Stadia game streaming service today. Anyone with a Gmail address can sign up, and Google is even providing a free two-month trial of Stadia Pro as part of the launch. It comes just two months after Google promised a free tier was imminent, and it will mean anyone can get access to nine titles, including GRID, Destiny 2: The Collection, and Thumper, free of charge.

This is exactly the news I’ve been waiting for! Excellent.


Now is a great time to make some mediocre art

Practicing simple creative acts on a regular basis can give you a psychological boost, according to a 2016 study in the Journal of Positive Psychology. A 2010 review of more than 100 studies of art’s impact on health revealed that pursuits like music, writing, dance, painting, pottery, drawing, and photography improved medical outcomes, mental health, social networks, and positive identity. It was published in the American Journal of Public Health.

What do we hear when we dream?

[R]esearchers at Norway’s Vestre Viken Hospital Trust and the University of Bergen conducted a small study to quantify the auditory experience of dreamers. Why? Because they wanted to “assess the relevance of dreaming as a model for psychosis.” Throughout history, they write, psychologists have considered dreamstates to be a model for psychosis, yet people experiencing psychosis usually suffer from auditory hallucinations far more than visual ones. Basically, what the researchers determined is that the reason so little is known about auditory sensations while dreaming is because, well, nobody asks what people’s dreams sound like.

This makes sense, if you think about it. The advice for doing online video is always that you get the audio right first. It would seem that it’s the same for dreaming: that we pay attention more to what we ‘hear’ than what we ‘see’.



How boredom can inspire adventure

Humans can’t stand being bored. Studies show we’ll do just about anything to avoid it, from compulsive smartphone scrolling right up to giving ourselves electric shocks. And as emotions go, boredom is incredibly good at parting us from our money – we’ll even try to buy our way out of the feeling with distractions like impulse shopping.

Erin Craig (BBC Travel)

The story in this article about a prisoner of war who dreamed up a daring escape is incredible, but does make the point that dreaming big when you’re locked down is a grat idea.


But what could you learn instead?

“What did you learn today,” is a fine question to ask. Particularly right this minute, when we have more time and less peace of mind than is usually the norm.

It’s way easier to get someone to watch–a YouTube comic, a Netflix show, a movie–than it is to encourage them to do something. But it’s the doing that allows us to become our best selves, and it’s the doing that creates our future.

It turns out that learning isn’t in nearly as much demand as it could be. Our culture and our systems don’t push us to learn. They push us to conform and to consume instead.

The good news is that each of us, without permission from anyone else, can change that.

The Three Equations for a Happy Life, Even During a Pandemic

This column has been in the works for some time, but my hope is that launching it during the pandemic will help you leverage a contemplative mindset while you have the time to think about what matters most to you. I hope this column will enrich your life, and equip you to enrich the lives of the people you love and lead.
